The amfAR Gala was packed with our favorite celebs and we saw so many stunning looks. From Katy Perry to Heidi Klum, we can’t decide who had the best beauty — what do you guys think? VOTE.

Alessandra Ambrosio, 35, Katy Perry, 31, Rosie Huntington-Whiteley, 29, and Heidi Klum, 42, are just four of the many gorgeous celebs that attended the 23rd amfAR Cinema Against AIDS Gala in Cannes. We saw so many stunning hairstyles and beauty looks, we can’t decide which one was our favorite! What do you guys think? VOTE.

The Cannes Film Festival literally brings out the best in people. We see the most stunning dresses and gorgeous beauty looks. Alessandra looked hotter than ever on the red carpet in a sheer black plunging gown with a thigh-slit on the side. Not only did we love her dress, her hair and makeup was so on point. She opted for a sexy and sultry look when she let her hair down in loose tousled waves. We love her dark and edgy smokey eye, she looks so punk — we’re obsessed.

While Katy rocked quite the outrageous red organza Marchesa gown, her makeup made up for it. She parted her hair in the middle and slicked her hair back so tight into a neat, low bun. Her updo was so sleek and perfect, we didn’t see one single flyaway. Katy topped her entire look off with a bright red lip and a thick cat eyeliner — it was amazing.

Rosie always looks flawless, we don’t know how she does it! She arrived in a silk Galvan silver dress that hugged her petite frame perfectly. Rosie also opted to part her hair in the middle and we love the way her soft, straight hair looks, especially her little flipped ends. She used a brown eyeshadow and she matched her lips to it, by rocking a glossy nude, brown lip.

Heidi looked flawless as always in a slicked back low bun with little wisps around her face. She went with a dark smokey eye and extra thick eyeliner and it was such a cool edgy contrast against her yellow gown!
